Forensically

Inspired by the concept of a magnifying glass, Forensically helps you detect if a photo has been tampered with.

Forensically arms the journalist with a number of tools that together can help identify inconsistencies within an image. These include:

Clone detection: highlights similar regions within an image, which can be a good indicator that a picture has been manipulated using a clone tool.

Error level analysis: compares the original image to a recompressed version. This can make manipulated regions stand out in various ways. For example, they may be darker or brighter than similar regions which have not been manipulated.

Noise analysis: using a separable median filter, this tool isolates noise, which can be useful for identifying if an image has been airbrushed, deformed, warped, and more.

Level sweep: allows you to quickly sweep through the histogram of an image by magnifying the contrast of certain brightness levels. One use of this tool is to make edges that were introduced when copy pasting content more visible.

Thumbnail analysis: shows the hidden preview image inside the original image (if there is one), for comparison with the image that you are investigating.
